2009 * @handle_type: the handle type for the channel, or %TP_UNKNOWN_HANDLE_TYPE
2010 * if you don't care about the channel's target handle type
2011 * @first_property_name: %NULL, or the name of the first fixed property,

2014 * Returns all the channel classes that a client can request for the connection
2015 * @connection, of the type identified by @channel_type, @handle_type and the
2016 * fixed properties list.
2017 * The classes which are compatible with a fixed properties list (i.e. those
2018 * that will be returned by this function) are intended as those that do not
2019 * contain any fixed property other than those in the list; note that this
2020 * doesn't guarantee that all the classes compatible with the list will contain
2021 * all the requested fixed properties, so the clients will have to filter
2022 * the returned list themselves.
2023 * If @first_property_name is %NULL, only the classes with no other fixed
2024 * properties than ChannelType and TargetHandleType will be returned.
2025 * Note that this function may return %NULL without performing any lookup if
2026 * @connection is not ready. To ensure that @connection is always ready,
2027 * use the empathy_dispatcher_find_requestable_channel_classes_async() variant.
2029 * Return value: a #GList of #GValueArray objects, where the first element in
2030 * the array is a #GHashTable of the fixed properties, and the second is
2031 * a #GStrv of the allowed properties for the class. The list should be free'd
2032 * with g_list_free() when done, but the objects inside the list are owned
2033 * by the #EmpathyDispatcher and must not be modified.
